The Al2O3 content of the Fire clay Brick is from 30-48%.During the manufacturing,first mix the clay chamotte with refractory clay powder,then prepared with clay aggregate into dry mud,high pressure molding,sintering at about 1400C.Under high temperature,the fire clay bricks show weakly acidic,and the ability of resistance to alkaline slag erosion is poor,but with the increase of the content of Al203,the thermal stability of fire clay bricks is better than silica brick, magnesia brick and so on.
Fireclay brick is made from clinker clay by mixing, forming, drying, sintering and matching characterized by good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
Advantage
1. Good resistance to corrosion and abrasion,
2. Perfect thermal shock resistance,
3. Good spalling resistance,
4. High mechanical strength,
5. Good volume stability under high temperature,
6. Excellent thermal performance, and acid resistance.
Application:
1) Cement and other building materials industry kiln back insulation;
2) Petrochemical, metallurgical, ceramics, glass industry, the furnace lining insulation;
3) Heat treatment furnace backlash insulation;
4) Non-ferrous metal industry back insulation;
5) High temperature reaction, heating equipment back insulation.
Low porosity clay bricks can be applied to steel, nonferrous metals, glass, cement, ceramics, pertrifaction, machinery, boiler, light industry, electric power, war industry and other economic filed, which is the indispensable basic material to ensure above production running and technological development, it plays an incomparable important role in the development of high temperature industrial production.
